The sprawling Texas Panhandle estate represents close to 50 years of dedication from Pickens, the oil magnate who died Wednesday at the age of 91. He shaped the ranch into "a wildlife paradise with spectacular water features and enhancements suitable for a king," according to Hall's entry and Hall. It is on the market with a quotation price of $ 250 million.

The 64,809-acre property's main gathering area is the 25,000-square-foot cabin, which has a suite with master bedroom, at least three fireplaces, a library with a spiral staircase, 30-seat theater, wine cellar and more, according to the listing.

It is also a separate 6,000 square foot family home, built in 2009, with five bedrooms and five bathrooms. The interior is finished with oak flooring and accent beams, and the living room is complemented by around 2,500 square feet of verandas and patios.

A two-story rustic pub has a games room, bathroom, kitchenette and fitness area, plus two sleeping areas and a fireplace.

The Canadian River flows along the northern boundary of the ranch, and Pickens made many improvements to create a 12-mile network of streams, lakes, waterfalls and ponds. There are also many quail and deer feeders. These features have helped make the property fantastic for hunters, with white deer, antelope, pigeon, turkey and waterfowl found there, in addition to what Pickens is said to have described as "the world's best quail hunting."
